Abstract
PURPOSE: To improve channel separation greatly by supporting an armature with a supporting part via a damper and by providing this damper with a groove which reduces mutual interference between left and right vibrations when the armature vibrates.
CONSTITUTION: A cartridge 20 consists of a magnetic circuit 21 and a vibration system 22; a couple of platelike yokes 23 and 24 and a magnet 25 sandwiched between those yokes are fixed to the magnetic circuit 21, and a pole piece 26 is also fixed to the yoke 23. Then, a suspension wire 35 pulling a cantilever toward a damper 34 is provided connecting with the rear end of the cantilever 28. The magnet 25 as an armature is supported with the wire 35 as a supporting part via the damper 34. Further, the damper 34 is constituted by forming nearly crossed grooves 41W44, crossing mutually centering on a through hole 39 for the wire, in the top surface of a cylindrical main damper body 38. Thus, the cartridge providing high sound quality is obtained.
